Zoa growing on brain coral base

[HKHAIR]

Hi.. this is my first tank and first time posting so sorry if I’m posting in the wrong place. Is this a zoa growing on my new brain coral? And if so do I just leave it or can it be moved to a new frag?

Hard to tell without a closer picture.

Blown up it certainly looks like a zoa. What happened with it?
